Hi All,

Thought I would post my experience changing out the factory wheel nuts. I have Kalimnos 20" wheels on my 2013 XKR and I noticed that one or two of the wheel nuts were difficult to get a 19mm socket onto so assume that rattle guns have been used before I took custody of her.

Based on threads here and the other Jag forum ;p I decided to purchase the Mitsubishi chrome nuts, part number MB579290. I got them for an amazing price from an ebay seller in Australia called Tufoptions who was cheap and shipped incredibly fast. Be aware - the Mitsubishi and Toyota nuts are 21mm rather than 19mm with the Jaguar ones - the factory tool will no longer fit (as mentioned in a few posts in this thread) so you will need a different tool or socket to work with the new nuts and keep in the car if something unfortunate happens.


Removing the wheels I compared how deep the Jaguar nuts sat in the wheels compared to the Mitsubishi ones (Mitsubishi are longer below the shank):




To get a level of comfort that with the various metals involved expanding at different rates these wouldn't end up with the wheels slightly loose (mentioned in the F-Type forum) I checked the depth that the rotors are countersunk for additional clearance:


...and confirmed with a friend who is a professional mechanic who gave it the thumbs up.

Being the CDO person that I am (CDO is like OCD, but the letters are in the correct order) I managed to track down an aerospace washer the correct size to give the extra depth clearance as per factory and have fitted these stainless washers underneath the captive washers on the Mitsubishi nuts:


These (Part Number AN960C1216) are from a company called Australian Aerospace Engineering, their webshop has a US warehouse as well.

Finally, I purchased a long 1/2' extension socket handle and plastic coated 21mm socket bit which are nestled in the boot / trunk in case they are required whilst enjoying the pace and to lesser extents grace and pace

Hope this may help others wanting or needing to make the change.

 

You stated that "one or two" OEM wheel nuts were buggered. So, 18 or 19 were still good. I don't understand why you bought 20 new Mitsubishi nuts, 20 special washers, and new tools. All of that must have cost well over US$100. You could have saved a lot of time and money simply by buying two new OEM Jaguar lug nuts.

All you have to do to protect your nuts is to not let anyone touch them unless they do it by hand with your wench.

Sorry, couldn't resist. Seriously, it's your money, your car, and your choice.

Both of my Jags (bought used) still have all the OEM lug nuts and they're like new. I make sure that tire techs use my 19mm socket and hand tools to R&R the wheels. The box of 20 Toyota nuts and new tools that I bought years ago after reading all the horror stories on the Forum are still sitting on a shelf in my garage.

 

I hear ya Stuart. I had the same issue but I realized this AFTER I got a flat tire and could not get one of them off with the hand wrench. Needed one of them special lug nut removal sockets. I didn't want that to happen again so I replaced them all. Easy and cheap.

 

That's a real bummer.

When I had my wheels refurbished a few years ago, I removed them myself and checked all the lug nuts at that time. I took the wheels to the shop and left the car on jackstands. I ceramic coated the refurb'd wheels before I put them back on the car to make it easier to remove the brake dust.

 

Logic definitely aligns with you @Stuart S But I got to buy tools and tinker with my car - and now I can let anyone touch my nuts as I choose haha
Part of it was to be a little project with the new toy as well, though to be honest I probably would have enjoyed the "hole saw project" to remove a knackered wheel nut had the situation arisen.

 

Me, I just bought those Toyota one-piece nuts hailed in that other thread.
